Special Issue Information

Dear Colleagues,

Airborne particulate matters suspended in air can be divided in coarse (PM < 10 μm, PM10), fine (PM < 2.5 μm, PM2.5) and ultrafine particles (PM < 0.01 μm, PM0.1) based on size. Studies on air pollution and its health effects have been focused greatly due to that ambient air pollution, particularly PM2.5 (aerodynamic diameter less 2.5 micrometers), was the fifth leading risk factor for global mortality. The PMs were originated from a variety of sources including anthropogenic origins such as power, automobile exhaust, combustion, mining, industrial sources, Numerous factors determine the toxicity of the particles because of their heterogeneous components, such as transition metal ions, organic compounds mostly polycyclic aromatic hydrocarbons (PAHs). Until now toxicological mechanism of the ambient particles is not very clear, oxidative stress theory induced by the PMs is the widely accepted theory.   Oxidative stress induced by the components of the ambientes can be used as predictor of adverse health impacts associated with PMs exposure.

We are now trying to organize a special issue on the Journal of Atmosphere to illustrate the oxidative potential induced by ambient particles, and provide more data on the toxicological mechanism of the particles.

The scope of the issue will include but are not limited to, characterization of ambient particles, oxidative stress induced by different components of particles, new methods on assess health risks.

In this Special Issue, we expect to gather high-level studies that allow us to interpret the oxidative stress caused by ambient particles in relation to the different diseases.

In order to reveal the pollution characteristics and sources of PM2.5, in this study, we collected PM2.5 filter membrane samples in Shihezi continuously from December 2020 to January 2021, and analyzed 10 kinds of water-soluble inorganic ions (WSIIs) and 24 inorganic elements (IEs), as well as organic carbon (OC) and elemental carbon (EC). The sources and transport paths of PM2.5 were also analyzed via PMF modeling and backward trajectory clustering analysis. The results show that, in winter, Shihezi can have a mean PM2.5 mass concentration as high as 164.69 ± 76.48 μg/m3, and the PM2.5 mass concentration on polluted days is 3.3 times that of clean days. Water-soluble inorganic ions (WSIIs), total carbon (TC), and inorganic elements (IEs) make up the percentage of PM2.5 mass concentration by 64.9%, 9.3%, and 2.6%, respectively. SO42−, NO3−, and NH4+ (SIAs) are the major WSIIs, accounting for 91.0% of the WSII concentration. The heavier the pollution, the more SIAs contribute to PM2.5. The OC mean mass concentration is 14.04 ± 5.32 μg/m3. As the winter pollution becomes worse and worse, the value of OC/PM2.5 decreases constantly while that of SOC/OC follows an opposite trend. During the process of heavy pollution in Shihezi, the secondary transformation of total carbon cannot be ignored. The positive definite matrix factorization (PMF) model result suggests that the main pollution origins of PM2.5 in Shihezi City comprise secondary sources, coal-burning sources, motor vehicle sources, industrial sources, and flying dust sources. The backward trajectory clustering analysis denotes that the winter pollution in Shihezi mainly comes from the local pollutants in Manas and the short-distance transport of pollutants from the Urumqi-Changji Region.

Allergenic pollen protein can be released from pollen grains and suspended in the air to cause allergenic reactions. However, the allergenic protein and its relationship with redox trace elements in ambient size-resolved particles has not been reported. Ambient size-resolved particles in Shanghai’s atmosphere were sampled during the Platanus pollen season in the spring season of 2017. Planatus pollen protein 3 (Pla a3) and redox trace elements in the ambient particles were investigated and their relationship was analyzed. Our data demonstrated that the mass level of the Pla a3 in the size-resolved particles ranged from 0.41 ± 0.28 to 7.46 ± 2.23 pg/m3, and decreased with the size range. Mass concentrations (ppb) of crustal elements (Fe, Al, Ca, Mg, Na) in the size-resolved particles ranged from 20.11 ± 9.87 to 1126.22 ± 659.51, while trace elements (V, Cr, Mn, Co, Ni, Cu, Zn, Ga, As, Se, Rb, Sr, Cd, Cs, Ba, Pb) varied from 0.05 ± 0.03 to 57.53 ± 19.7. Mass levels of these trace elements decreased according to particle size. The Abundance of redox trace elements, including Fe (R2 = 0.82), Mn (R2 = 0.54), Cu (R2 = 0.61), Ba (R2 = 0.82), and Pb (R2 = 0.82) in the size-resolved particles was significantly related to that of Pla a3, and our data implied redox trace elements might take syngenetic effects on the allergenicity induced by Pla a3 protein.
